Description

Technical Field

[0001] This invention belongs to the field of valve block manufacturing technology, specifically relating to a compressive strength testing device for valve blocks used in the production of new energy vehicles. Background Technology

[0002] The "valve block" in a car's braking system is a core hydraulic control unit, especially in advanced Electronic Stability Program (ESP) or Electronic Stability Control (ESC) systems. Simply put, the valve block is the actuator of the "heart" and "brain" of the ESP / ESC system. It is responsible for receiving instructions from the control unit and achieving various advanced braking functions by precisely adjusting the brake fluid pressure of each wheel.

[0003] Typically, it's a metal block (usually made of aluminum) containing a complex network of channels, valves, and solenoids. Externally, it connects to brake fluid lines from the master cylinder, lines to the four wheel cylinders, and wiring harnesses for various sensors (such as pressure sensors). The core components mainly consist of multiple high-speed switching solenoids, a pump motor, an accumulator, and pressure sensors; it's usually located in the engine compartment, close to the master cylinder (the one pushed when the driver presses the brake pedal), and tightly integrated with the ESP / ESC control unit (ECU) to form a module. Therefore, it's often referred to as the "ESP hydraulic unit" or "ESP pump." When performing pressure testing on the valve block, it is necessary to position the valve block to ensure that the downward pressure of the top pressure drive device is accurate and uniform, preventing errors in the final pressure test data due to position deviation. Since the valve block is a frame used to install instrument components, the holes in its internal installation area are not uniform. Only by performing pressure testing at the accurate position can the most accurate pressure data of the valve block be fed back. Summary of the Invention

[0004] The purpose of this invention is to provide a compressive strength testing device for valve block production in new energy vehicles, so as to solve the above-mentioned problems.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a compressive strength testing device for valve block production in new energy vehicles, comprising a control console, wherein a base is provided at the bottom of the control console and a positioning and receiving component is provided on the top of one side of the base, and further comprising: A positioning component is used to adjust the position of the valve block placed on the positioning receiving component; The mounting bracket, drive unit, drive shaft, and pressure member are mounted on the base and the drive unit is mounted on the top of the mounting bracket. The drive shaft is located in the center of the drive unit and is connected to the drive unit for transmission and moves downward under the drive of the drive unit. The pressure member is movably mounted on the bottom of the drive shaft. The center points of the drive shaft, the pressure member, and the positioning and receiving assembly are on the same vertical line.

[0006] Preferably, the positioning and receiving component includes: The outer casing is mounted on top of the base and recessed into the base. Electric actuators, the number of which is set to a certain number and arranged in a circular array inside the housing; A pressure receiving platform is fixedly installed inside the outer shell and is located in the center of several electric push rods. The top plane of the pressure receiving platform is at a lower level than the top surface of the outer shell. The outer ring component is fixed to the top of several outer shells and moves up and down as the outer shells are driven. The movable connector group and the ring-shaped component group are provided. The movable connector group consists of several trapezoidal connectors forming several circular rings that are hinged to multiple ring-shaped component groups.

[0007] Preferably, the multiple trapezoidal connectors of the outermost movable connector group are hinged to the inner ring of the outer ring member, so that the outer ring member, the movable connector group and the ring member group form a mechanism that can realize conical extension and retraction.

[0008] Preferably, the pressure receiving platform has multiple grooves inside, and the multiple grooves are adapted to the annular component assembly. An annular electromagnet is fixedly installed inside the groove, and the annular electromagnet attracts the corresponding annular component of the annular component assembly to form a conical groove.

[0009] Preferably, the distance from the top surface of the annular electromagnet to the top surface of the pressure receiving platform is equal to the distance from the bottom surface of the annular component assembly to the bottom surface of the trapezoidal connector, so that the movable connector assembly and the groove on the annular component assembly and the pressure receiving platform form a seamless engagement.

[0010] Preferably, the positioning component includes four mounting seats arranged in a circular array on the outer edge of the positioning receiving component. An electric push rod is provided on the side of the mounting seat near the center point of the positioning receiving component. A driven plate is fixed on the output shaft of the electric push rod and, when activated by the electric push rod, pushes and positions the valve block on the top surface of the positioning receiving component.

[0011] Preferably, the top of the drive shaft is provided with a top cover for disassembling the drive shaft.

[0012] The technical effects and advantages of this invention are as follows: According to the specifications of the valve block, a correspondingly sized annular electromagnet is energized and activated, thereby attracting one of the annular components in the corresponding annular assembly at its top to sink. The outermost ring, as the outermost ring of the top plane of the positioning and receiving component, forms a conical groove with one of the sinking annular components due to the unchanged support position of the electric push rod. The valve block slides towards the center through this correspondingly sized conical groove. After sliding, multiple electric push rods are activated, causing the outer ring to contract and align with the annular assembly at the same horizontal plane. This allows the movable connecting component group and the annular assembly to engage tightly, creating a new pressure detection plane below the top surface of the outer shell. The solid bottom of this plane absorbs the pressure from the pressure detection without damage. Furthermore, the entire process achieves automated positioning. When detecting smaller valve blocks, preliminary positioning using the conical groove can be performed first, followed by secondary positioning using the positioning component, preventing issues with insufficient automated positioning accuracy and dimensional coordination problems caused by excessively small valve blocks.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] This invention provides, for example Figures 1-5 The pressure resistance testing device shown is used in the production of valve blocks for new energy vehicles. It includes a control console 9, a base 3 at the bottom of the control console 9, and a positioning and receiving component 1 on the top of one side of the base 3. It also includes: Positioning component 2 is used to adjust the position of the valve block placed on positioning receiving component 1; Mounting bracket 5, drive device 6, drive shaft 8 and pressing component 4. Mounting bracket 5 is mounted on base 3 and drive device 6 is mounted on top of mounting bracket 5. Drive shaft 8 is located in the center of drive device 6 and is connected to drive device 6 for transmission and moves downward under the drive of drive device 6. Pressing component 4 is movably mounted on the bottom of drive shaft 8. The center points of drive shaft 8, pressing component 4 and positioning and receiving assembly 1 are on the same vertical line.

[0021] Specifically, the positioning and receiving component 1 includes: The outer casing 101 is mounted on top of the base 3 and recessed into the interior of the base 3; Electric push rods 102 are arranged in a circular array inside the housing 101. The pressure receiving platform 103 is fixedly installed inside the housing 101 and is located in the middle of several electric push rods 102. The top plane of the pressure receiving platform 103 is at a lower level than the top surface of the housing 101. The outer ring 104 is fixed to the top of several outer shells 101 and moves up and down as the outer shells 101 are driven. The movable connector group 105 and the ring component group 106 are provided. The movable connector group 105 is formed by several trapezoidal connectors 10 forming several rings that are hinged to the multiple ring component groups 106.

[0022] Specifically, the multiple trapezoidal connectors 10 of the outermost movable connector group 105 are hinged to the inner ring of the outer ring member 104, so that the outer ring member 104, the movable connector group 105 and the ring member group 106 form a mechanism that can realize conical extension and retraction.

[0023] Specifically, the pressure receiving platform 103 has multiple grooves 107 inside, and the multiple grooves 107 are adapted to the annular component assembly 106. An annular electromagnet 108 is fixedly installed inside the groove 107, and the annular electromagnet 108 attracts the corresponding annular component of the annular component assembly 106 to form a conical groove.

[0024] Specifically, the distance from the top surface of the annular electromagnet 108 to the top surface of the pressure receiving platform 103 is equal to the distance from the bottom surface of the annular component assembly 106 to the bottom surface of the trapezoidal connector 10, so that the movable connector assembly 105 and the groove 107 on the annular component assembly 106 and the pressure receiving platform 103 form a seamless engagement.

[0025] Specifically, the positioning component 2 includes four mounting seats 203 arranged in a ring array on the outer edge of the positioning receiving component 1. An electric push rod 202 is provided on the side of the mounting seat 203 near the center point of the positioning receiving component 1. A driven plate 201 is fixed on the output shaft of the electric push rod 202. When the electric push rod 202 is activated, it pushes and positions the valve block on the top surface of the positioning receiving component 1.

[0026] A top cover 7 is provided on the top of the drive shaft 8 for disassembling the drive shaft 8.

[0027] Working principle: When using this invention, the operator places the valve block on the positioning and receiving assembly 1. According to the specifications of the valve block, the corresponding size of the annular electromagnet 108 is energized and activated, thereby attracting one of the annular components in the corresponding annular component group 106 at the top of the valve block to sink. The outer ring 104, as the outermost ring of the top plane of the positioning and receiving assembly 1, forms a conical groove with one of the annular components in the sinking annular component group 106 because the support position of the electric push rod 102 remains unchanged. The valve block slides towards the center through the corresponding size conical groove. After sliding, multiple electric push rods 102 are activated to drive the outer ring 104 to contract and be on the same horizontal plane as the annular component group 106. This makes the movable connecting component group 105 and the annular component group 106 tightly engaged with each other, and they are in a new pressure detection plane that is lower than the top surface of the outer shell 101. The bottom of this plane is a solid surface that can withstand the pressure from the pressure detection without damage. Based on Embodiment 1, multiple positioning components 2 can be used to accurately position the valve block that has slid into the center. The electric push rod 202 drives the driven plate 201 to move inward, pushing the valve block at the center position to be further fixed. The entire process activates the corresponding annular electromagnet 108 according to the valve block of different specifications, and realizes the switching of the horizontal support during pressure detection to achieve the switching between solid and hollow. The hinge of multiple trapezoidal connectors 10 can realize the formation of a conical groove without affecting the overall bearing effect. During this process, the number of annular components in the annular component group 106 can be determined according to the actual conventional size of the valve block.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
